ObjectivesTo systematically review the disease burden of osteoporotic fracture (OPF) in China.MethodsWe searched PubMed, EMbase, CNKI, WanFang Data and VIP database for observational studies of the disease burden of osteoporosis in China from inception to Jan 30th, 2018. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies.The descriptive analysis was used to analyze the economic burden of OPF in China.ResultsA total of 23 studies were included. The average cost of OPF was 27 561.27 yuan. Women were more prone to OPF than men. Hip and spinal fractures were the diseases which had higher average hospital costs.ConclusionsWomen are more prone to osteoporotic fractures than men. The higher hospital costs of OPF may cause the reason for growing financial burden of patients. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify conclusions.
ObjectivesTo systematically review the complications of knee arthroscopic surgeries in China.MethodsWe searched PubMed, EMbase, CNKI, WanFang Data and VIP databases to collect cross-sectional studies on the complications of knee arthroscopic surgeries in China from inception to March 1st, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 36 studies involving 20 740 cases were included. The results of meta-analysis showed the incidence rate of complication in knee arthroscopic surgeries in China was 9.71% (95%CI 8.20% to 11.23%). Subgroup analysis showed that the complication incidence rates in the eastern, central and western regions were 10.04% (95%CI 8.00% to 12.14%), 9.67% (95%CI 6.57% to 12.76%) and 7.47% (95%CI 6.20% to 8.73%). The complication incidence rates in the upper first-class and non-upper first-class hospitals were 9.50% (95%CI 7.83% to 11.17%) and 10.95% (95%CI 6.75% to 15.14%). The top 3 complication types with highest incidence rate included joint effusion［2.16% (95%CI 1.44% to 2.87%)］, accidental injury of native structures［1.49% (95%CI 0.96% to 2.03%)］ and hemorrhage［1.43% (95%CI 1.01% to 1.84%)］. Other severe complications including neurovascular injury, thrombosis diseases and infection were 0.06% (95%CI 0.02% to 0.11%), 0.33% (95%CI 0.19% to 0.48%) and 0.08% (95%CI 0.03% to 0.13%).ConclusionsCurrent evidence shows that the complication incidence rate of arthroscopic surgeries in China is relatively high and the complication type is complex and varied. Due to the quantity and quality of the included studies, more high-quality studies are required to verify the above conclusions in future.
ObjectiveTo review research progress in the anterolateral ligament (ALL) of knee, and provide a clinical reference for diagnosis and treatment of ALL injury.MethodsThe literature on the diagnosis and treatment of ALL injury was widely reviewed. The incidence, anatomy, biomechanics, injury mechanism, and treatment status of ALL were summarized.ResultsThe ALL contributes to the effect of controlling the internal rotation and anterior translation of the tibia, which affects the axial migration of the knee. ALL injury can be diagnosed according to the signs and MRI examination. Currently, no consensus exists for the surgical indications of ALL injury, but most surgeons tend to perform ALL reconstruction in patients requiring anterior cruciate ligament (ACL) reconstruction or revision surgery with higher pivot-shift tests. At present, various techniques have been used for ALL reconstruction, and there is no optimal technique. In addition, the long-term effectiveness of ALL reconstruction is unclear due to the lack of high-quality studies and long-term postoperative follow-up.ConclusionThe ALL contributes to maintaining knee stability, and the ALL reconstruction technique and its effectiveness still need further research.
